Patent JP-H06164428-A (JP)
Title: Electronic and optical signal-linearization predistorter
Inventor: HENRII EI BURAUBERUTO
IPC: H04B1/62
Filed: 1993-07-21
Abstract: PURPOSE: To provide an electronic circuit which can obtain a linear output from an amplitude modulating transmitter, such as the amplifier or semiconductor laser having inherent distortion. CONSTITUTION: A front-end compensator compensates the distortion of a nonlinear device by adding the preceding distortion signal having the same magnitude and the opposite sign. The route of the compensator is divided into a primary route 13 for directly supplying input signals to the device and a secondary route 14 having a time lag for compensating delays in the route 14. Since the secondary route 14 offsets the distortion of an output device, the route 14 generates preceding distortion that is recoupled with primary signals in a proper phase and amplitude. The distortion generator 15 of the secondary route 14 generates adjustable amplitude mutually modulated signals. In order to compensate the dependency of the distortion of the nonlinear device on the frequencies of a basic signal and distortion, filters are used before and after the distortion generator 15.  The phase of a distortion signal is adjusted so that the phase may maintain a proper phasic relation with the distortion of the device.

Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To obtain a tourmaline composition unglazed pottery having an adsorbing function provided with a self-reproducing ability and an electrode activity based on crystal structure by including a clay and a specific amount of tourmaline. SOLUTION: This tourmaline composition unglazed pottery contains a clay such as Kibushi clay, potter's clay or kaolin and 5-50 wt.% of tourmaline. The tourmaline composition unglazed pottery having an apparent density of 1.7-1.9 g/cm<3> is obtained by mixing a prescribed amount of tourmaline having an average particle diameter of 0.3-100 μm with a prescribed amount of a clay having an average particle diameter of 1-20 μm, molding the mixture, drying the molded product and subsequently calcining the dried molded product at 700-1,300 deg.C. The tourmaline composition grazed pottery is coated with an alkali glazing agent and/or a borosilicate glazing agent suitable for low temperature sintering and subsequently sintered at 800-1,200 deg.C to produce the tourmaline composition pottery. The tourmaline is a bipolar crystal, preferably schorl tourmaline and lithium tourmaline.  The catalyzing ability, electric field, magnetic field and far IR light-radiating ability act to decompose water and give an electron to H<+> to produce [H].

Title: Evaluation method of substrate for bulk wave device
Inventor: KADOTA MICHIO
IPC: G01N29/00
Filed: 1993-07-21
Abstract: PURPOSE:To allow measurement of the bulk sound velocity of a substrate under the state of non-piezoelectric ceramic without requiring any polarization or formation of electrode by applying ultrasonic wave to a sample substrate and causing interference between pulse waves reflected on the surface and the rear. CONSTITUTION:A high frequency signal from a tracking generator is converted by an RF switch into a burst wave which is passed through a circulator and applied to a plane wave acoustic lens 1 thence radiated, as an ultrasonic wave, to a sample substrate 4. Reflection waves P1, P2 from the surface and the rear of the sample 4 are converted through a lens 1 into electric signals which enters into a spectrum analyzer through an attenuator gate. In this regard, the pulse reflection waves P1, P2 are caused to interfere each other by sweeping the applying pulse frequency. The period of interfering frequency is proportional to the bulk wave sound velocity of the sample 4, which is determined by multiplying the period of interference frequency by two times of the thickness of the sample 4.
